Would be great if we could see which shows are currently airing new episodes vs those that are finished. Perhaps a small indicator icon on the anime portrait? Similar to how there is an icon for items in queue. Bonus if it shows what in your queue is airing as well.

For myself, I'm one that prefers to wait until a show finishes airing then marathon it. Right now you have to keep checking the show page to tell if it's finish airing.
